Cardiac resynchronization therapy in systolic heart failure ...
2024年7月12日 · Cardiac resynchronization therapy (CRT) is a modality of cardiac pacing that provides simultaneous or nearly simultaneous electrical activation of the LV and right ventricle (RV) via stimulation of the LV and RV (biventricular pacing) or LV alone.
Indications for Cardiac Resynchronization Therapy:
They are different in presentation as they specifically address which type of device therapy is indicated (CRT-pacemaker [CRT-P], CRT-defibrillator [CRT-D], or implantable cardioverter-defibrillator [ICD]) based on NYHA functional class and QRS duration and morphology.
